The damage to the ultralight was attributed to the impact with the ground. There is no indication that the aircraft experienced a malfunction before the accident. The tests performed on the parts sent to the TSB Engineering Branch Laboratory ruled out the possibility of a structure break-up in flight. The passengers who boarded the ultralight aircraft were to receive training as part of a familiarization flight. Such ultralight flights are neither supervised nor defined as they are for an aeroplane. It is therefore hard to distinguish between a familiarization flight and a simple ultralight tour. The prevailing conditions in terms of winds and terrain profile were conducive to low-level mechanical turbulence. The pilot probably encountered turbulence conditions that he was unable to manage, resulting in loss of control of the aircraft. The following laboratory report was completed:Analysis The damage to the ultralight was attributed to the impact with the ground.

The prevailing conditions in terms of winds and terrain profile were conducive to low-level mechanical turbulence. The pilot probably encountered turbulence conditions that he was unable to manage, resulting in loss of control of the aircraft. The following laboratory report was completed: The winds were blowing at 9 to 18 knots, possibly causing low-level mechanical turbulence. The pilot probably encountered turbulence conditions that could have caused a loss of control.Findings as to Causes and Contributing Factors The winds were blowing at 9 to 18 knots, possibly causing low-level mechanical turbulence. The pilot probably encountered turbulence conditions that could have caused a loss of control. A familiarization flight is neither defined nor supervised for ultralights. It is hard in this kind of operation to distinguish between a so-called familiarization flight and an ultralight tour.Other Findings A familiarization flight is neither defined nor supervised for ultralights. It is hard in this kind of operation to distinguish between a so-called familiarization flight and an ultralight tour. In the document Flight 2005 Implementation Plan, Transport Canada indicates that it intends to bring about a 10-per-cent reduction in the accident rate and loss of life in recreational aviation by 2005. To achieve its objectives, Transport Canada wants to improve ultralight training by developing a ground and flight instruction program, developing guides and manuals, and developing a refresher training program for recreational flight instructors. On 17 March 2000, the Quebec Region of Transport Canada's Civil Aviation Directorate held a symposium for ultralight flight instructors. A stakeholder working group was set up to develop a ground and flight training program. This exercise is being conducted nationwide. Several notices of proposed amendment are under review by Transport Canada with a view to introducing a new qualification allowing the carriage of passengers on board ultralight aircraft.Safety Action In the document Flight 2005 Implementation Plan, Transport Canada indicates that it intends to bring about a 10-per-cent reduction in the accident rate and loss of life in recreational aviation by 2005.
